Agree with the above. 20 year resident here and Nov can be cool or it can be hot. Since you are from way up north from here, you probably will be fine to be in the waterparks but not the locals. It's usually a bit cool for us here to be swimming. The waters are "heated" but they are still chilly to about 84 degrees all around WDW.
We are predicted to have a wet winter this year so it could be a rainy Nov. Check about 2 weeks prior to coming to see weather predictions.
